Hi,

I am experiencing a critical issue with my app (dbMobil) in its published state. When the app is installed via TestFlight, it works without any problems and no errors can be detected. However, when downloading the same app from the App Store, it immediately crashes for many users without displaying any error message, directly at app start.

This issue also occurs on my own test devices:

TestFlight version: works flawlessly

App Store version: crashes immediately upon launch

It appears that there must be a difference between the version I submitted and published via TestFlight and the one currently available on the App Store.

Could you please provide me with feedback on what differences may exist between these two versions and where the cause of this issue might lie?

Thank you in advance for your assistance.

Thank you for the post and detailed description of the issue. I have checked both versions of the app on the App Store and TestFlight. Both versions have the same version 4.0.1 and the same build number 340.

Therefore, both versions appear to be the same app. However, the crash files indicate that there is a part in your code that calls abort. Unfortunately, since it is your code and symbols, I cannot pinpoint the exact location of the crash at this time. It appears that frame 8 is the culprit.

I recommend downloading the app from TestFlight and using your Xcode with your symbols to identify the crash or abort. I am happy to assist you in loading your app symbols to diagnose the issue.

Please let me know how I can help. However, I believe that if you use Xcode, connect the device, and debug the app, you will be able to resolve the issue quickly. I hope this information is helpful to you.

Thank you very much for your feedback and suggestions.

As an additional note, my development environment is Visual Studio 2022, and the app was developed as a multi-platform application for iOS and Android.

I am not entirely sure how I resolved the issue, but with the latest update it no longer occurs. The app now starts in the App Store environment just as it does in the TestFlight environment and no longer crashes.

I made two changes during the process:

re-downloaded all certificates (Distribution, Developer, Provisioning Profile) and added them again on my Mac.
re-integrated all additional packages.

After these steps, I uploaded the updated version to the TestFlight environment and subsequently submitted it for review in the App Store.
